To save you cleaning dishes yourself.

Muriatic acid can be used to clean dishwashers. Muriatic acid is very strong and should only be used occasionally for cleaning the dishwasher.

You can find septic tank cleaning guides on the following site: http://www.inspectapedia.com/septic/tankpump.htm. It is a very helpful resource.

I highly suggest the following: http://www.sears.com/appliances-dishwashers/c-1020017 and http://www.whirlpool.com/kitchen-1/dishwasher-%26-cleaning-2/dishwashers-3/102110034/.

Dishwashers do not get all heavily soiled items off, I would suggest soaking your dishes in a very hot sink with lots of hot water then washing them by hand.
